Ok, i've had this Walbro 255 lph fuel pump installed a couple of weeks now and as some of you know I had some problems with it. Eventually I resolved the problem by changing relays.
Now, I also changed my stock filter with the filter that came with it. The shape of it is different then stock. Stock has a L shape, walbro filter is a square.
I noticed my car wasn't starting immediatly and my fuel pump was very loud as well. So, a couple of days ago I was running low on fuel and I was pushing it but I felt the car choked and then eventually kept driving again. It felt like I was hitting the rev limiter, but I was at 3500rpm.
So, I think the problem with the new fuel pump is that if I push it, so much torque is created, that all my fuel end up at the back of the car. Making the fuel not being sucked in by fuel pump.
The location of the fuel filter was supposed to be in the opposite direction(facing the rear part of car, so no matter how much torque you make... you will always have fuel). Now with the new location it's facing the front of the car, it's possible that if you push it and create alot of torque the fuel will not be sucked in by the fuel pump.
To solve somewhat of the problems, I decided to get a new stock fuel filter at my toyo dealer for 8 bucks. I installed it just now and my car starts immediatly again and the noise is gone. Sounds like stock now.
When i'm running low on fuel again, I will push my car and see if this L shape the stock filter has, actually helps sucking in fuel.
If not, then people who are planning to buy an aftermarket fuel pump should buy a fuel pump that directly fits and has the filter faced the same way as stock. I've read on the MWR site that the PE 165lph is a drop in fuel pump and doesn't need any modifications. Most likely this will be the best fuel pump you can buy to avoid any hickups while pushing it on low fuel(1 cel left) on high boosted cars that created lots of torque, causing your car not to get fuel.
I'm not sure if Immo or G7celica experienced this, but I don't think C2Power stage 1 owners will have to worry about the problems I had.
That's it, I will let you guys know if I have any problems or get any problems now with my new filter.
